Gene Sperling, a senior economic adviser in the Biden administration, is leaving his White House role to join Vice President Kamala Harris' presidential campaign. His departure comes amid a downturn in U.S. stock markets, raising eyebrows about the timing of his transition. Sperling has been instrumental in managing the $1.9 trillion pandemic aid package and implementing significant economic relief measures, which President Biden credited for aiding millions of families. However, Republican critics argue that these pandemic programs have contributed to rising inflation, complicating the Biden administration's economic narrative. Sperling's strong working relationship with Harris, established during their previous collaborations, is expected to influence her campaign's policy direction. This is the second high-profile departure from the Biden administration in recent weeks, following Anita Dunn's move to support Harris' campaign efforts.
